This study investigates the noise levels and frequency characteristics associated with the cutting of duralumin using carbide circular saw blades. The noise level increases from approximately 85 dB during idling to approximately 92 dB during cutting, with peaks reaching 95 dB under overload conditions, particularly highlighting the significant increases in the high-frequency noise at approximately 8 kHz. Prolonged exposure to high-frequency noise can lead to hearing loss in humans, as noted in existing literature. To protect the hearing of field experts who set feed rates and monitor overload conditions by listening to sounds, and to enable novices to perform tasks, this study quantifies the expert's process of setting conditions and monitoring through frequency analysis. This will contribute to improving the work environment, protecting worker hearing and well-being, and enabling safe and efficient novice operations.
